' r AUTOMOBILE LOCK.

Application filed June '13,

venting the theft of automobiles and motor cars in general. I It is the principal object of the invention to provide a device of this class which is automatically. stopping the supply of gas to the engine if a person, other-than the owner or authorized driver of the vehicle is trying to operate the machine.

Another 'object of the invention is the provision of a device of' this character which is of a simple and therefore inexpensive construction and which may be readily applied to .any automobile of standard type.

A further object of the inventionis the provision of a device of this type which is capable, of adjustment in accordance with the predetermined weight of the driver authorized to operate the car.

These and other objects of the invention will become more fully apparent as the description proceeds and will then. be more specifically pointed out in the appended claims. i i i In the accompanying drawings, forming a material part of this disclosure:

Figure 1- is a side view of an automobile equipped with the device constructed according to the present invention, partly in section.

Figure 2 is a side view of-an auxiliary cylinder attached to the bottom of a car and the feed pipe valve co-operatingtherewith.

13 arranged within a chamber-14 under the seat. This piston is working in a vertical cylinder 15 and between the bottom of said Specification of Letters Patent. Patented Apr, 25, 19 22,

i with a movable base plate 12, has aipiston I cylinder and piston a strong spring .16-is v provided allowing up and down .movement of the plate 12 within certain limits. j

To the rear edge of the plate 12, one fend of a cable .17 is attached which is guided through a chamber 18 and the bottom of the car and over a guide roller '19 journaled 2 in the lower ends of a hanger 20' secured.

with its-upper end to the car bottom. 21.

To this bottom 21 isalso secured a bracket 22 'havinga dove-tailed groove 23 'in which is engaged a bar 24: of dove-tailed cross-sec? Y tion, and having a base 25. This bar 2 1- can be adjusted to, any position within the groove and-can be locked-in this position by means of a number of bolts 26 .v

Integrally made with the base 25 is an auxiliary cylinder 27. in which-a piston 28 is working, to theouter flange 29 of which the end of cable 17 is fastened. A-strong spring 30 is secured; with one endrtothe inner fiange31 of the piston 28, while its -1- other end is resting against the innerr'face I of the end wall of the cylinder. The cylinder 27 is provided at'its lower.

facewith a longitudinalslot 32 along which agraduation is showndesignated generally,

pipe 38 in which a butterfly valve. 39 isar- V ranged having, its angula'rstem AOextendmg out of and. above the pipe 38 into the path keeps the valve 39 normally closed.

The device operates as follows:

After the weight of the person authorized to drive the automobile or carrjhas-been determined, '(inthe presentinstance 1-50 pounds) the length of the cable 17 and the position of theauxiliary cylinder are ad- 1 justed so that the index finger 35 indicates on the scale 33 this weight andtheiend' of the cable is fastenedto the se'at'12. 'Inthis 1 position, the finger 35 will be in the path of 1 010 of finger35. A spring 41 is provided which the valve operating stem 40 and engage the same to hold the valve open to feed fuel from the tank to the engine.

If now the driver leaves his seat, the spring 30 will draw flange 31 of piston 28 and finger 35 out of engagement with the stem 40, and the valve 39 will be closed under the action of the spring tl when now a person of less \veightthan ltiO pounds occupies the seat and tries to start the engine, the finger 85 will not engage the stem 40 and no fuel will be fed to the engine and the valve will remain closed. If however a person of a greater weight than 150 pounds takes the seat and attempts to operate the car, the linger 35 will open the valve for an instant, will however not keep it in this position but pass it, and the valve will close automatically, so that any person of a greater weight than 150 pounds will not be able to start the engine and drive away with y a the car.

Having thus described my invention, what I claim as new and desire to protect by a United States Patent is:

1. A device of the class described, comprising an auxiliary cylinder, a butterfly valve in the fuel feed pipe of atom, means connected with said cylinder for automatically opening said valve upon the occupation of the seat of a car by a person having a predetermined weight, and means for allowing an adjustment of said valve opening means according to the weight of'the driver.

2. A device of the class described, comprising an auxiliary cylinder adapted to be adjustably secured to the bottom of a-car, a spring controlled means reciprocating in said cylinder and having a projecting meniber, a fuel feed controlling meanshaving an element projecting into the path of said projecting member for controlling the fuel supply, a'niovable seat and means connecting said seat with said reciprocating means, said reciprocating means being adjustable to engage said fuel controlling means when a person of a predetermined weight is occupying the drivers seat.

3. A device of the class described, comprising an auxiliary cylinder adapted to be adjustably secured to the bottom of a car, a spring controlled piston working in said cylinder, a seat having a movable base, means connecting said base with said piston, an operating arm on said piston extending to the outside of said cylinder, a butterfly valve within the fuel feed pipe of a car, a stein on said valve extending out of said' feed pipe into the path of said operating arm,

and means for, adjusting the point of'en gagement between said arm and-stem in accordance with the weight of the person to occupy the drivers seat.

4c. A device of the class described com prising a vertically reciprocating spring controlled base for a car seat,-an auxiliary cylinder having a longitudinal slot, a spring controlled piston Working in said cylinder,

a cable connecting said base with said piston, meansfor guiding said cable, a member secured to said piston projecting from the cylinder through the slot'thereof, a graduation near said slot, and means'for adjusting the position of said cylinder with respect to the car bottom, a butterfly valve within the fuel feed pipe of the car and a stem on said valve projecting into the path of said projecting member.

In testimony whereof I have affixed my signature.
